Why PDF to PNG Converter on sakutto is safe
Many online tools upload your files to external servers for processing. This tool never sends your PDF files to any server — everything is processed entirely in your browser.
* Some AI-powered tools require server-side processing. Tools that send data to a server will always notify you beforehand.
| Comparison | Typical online tools | sakutto |
|---|---|---|
| Where data is sent | Uploaded to external servers | Nowhere — processed in your browser |
| Data leak risk | Risk during transfer and server storage | No risk — no network transfer occurs |
| External traffic | File data travels over the internet | No file data appears in network logs |
| Offline use | Not possible (server required) | Works offline after initial load |
How browser-based processing works
- WebAssembly (WASM): Processes PDF files in your browser at near-native speed. No server communication occurs.
- Web Workers: Runs on a background thread separate from the main thread, so your browser stays responsive during processing.
- After processing, your browser automatically frees the data from memory. No PDF files remains outside your device.
For IT security teams: How to verify
You can verify that sakutto never sends your PDF files externally by checking the Network tab in your browser's DevTools while using the tool. You'll see that no requests involving your PDF files are made. This can also serve as documentation for your IT security team.
Frequently Asked Questions
Is my file sent to a server?
No. All processing happens entirely in your browser. Your PDF is never uploaded to any external server, so you can safely use this tool with confidential documents.
Should I choose PNG or JPG?
PNG is best for text-heavy PDFs and documents with detailed charts — it preserves every detail without quality loss. JPG is better for photo-heavy content or when you need smaller file sizes.
Are PNG files larger than JPG?
Yes. PNG uses lossless compression, so files are larger than JPG or WebP equivalents. Choose PNG when quality is your top priority, and JPG or WebP when file size matters more.
Which resolution (DPI) should I choose?
Standard (72 DPI) is fine for web and social media. Medium (150 DPI) works well for on-screen reading. High (300 DPI) is recommended for printing. Higher resolutions produce larger files.
Can I convert password-protected PDFs?
Password-protected PDFs are not currently supported. Please remove the password before uploading.
